fix(wallet/accounts): don't store derived account when it exists in app db

As discussed in #10326 and later in https://github.com/status-im/status-go/issues/1939, it turns out
that, when a user tries to add an account (from a seed phrase), while an account
with the same address (that the seed phrase would result in) exists in the application
state, the application would still go ahead and store the derived account in
status-go.

After that it still reports to the user that the 'Account already exits'.

This commit ensures that Status doesn't try to store the derived account when
the account already exists in the application database.

Fixes #10326
